How accurate is a negative HIV test after 40 days of possible HIV exposure? Currently, it has been over 8 weeks since my possible HIV exposure. I don’t have any symptoms. Should I keep testing for HIV until the six month window is over or was the HIV-1 RNA PCR result at 40 days enough?

It sounds like you’ve had two different kinds of HIV tests. The first kind, the one used by most clinics as a screening test, looks for antibodies produced by the immune system against the virus. Detectable antibody levels to HIV usually develop within two to eight weeks (the average is actually about four weeks), but it sometimes takes longer. This test will almost always be reliable three months after exposure, so to be on the safe side, we recommend a second HIV antibody test if the first was done before 90 days after exposure.

The second test you mentioned is the HIV 1 RNA PCR. This is an additional test sometimes performed for people with a high-risk exposure and symptoms of acute HIV disease. An exposure would be considered high-risk, for example, if the partner was known to be HIV positive. If this test was negative at 40 days after exposure, you did not become infected from the exposure you mentioned.

Having said that, I suggest considering how you will plan for HIV testing in the future. Depending on your circumstances, perhaps routine testing every 3-6 months would appropriate. This is because it is sometimes very difficult to determine how risky a given exposure might be. This would also be a good time to request screening for other sexually transmitted infections, and to review recommendations for immunizations (for example, for hepatitis B and HPV) with your doctor.

I know this is probably stupid but, I was fingering someone last Saturday night and I had a hangnail on my finger. The area was not bleeding, but I am wondering is this a possible HIV concern or is the chance of it too remote?

The risk of contracting or transmitting HIV (or any other STIs) through hand-to-genital contact is very slight and I’m not aware of any documented cases where this has been proven to transmit HIV.

Viral STIs such as HPV or HIV are spread primarily through anal and vaginal sex. Injecting drug users who share dirty needles and syringes are also at risk for HIV and, while it happens less often, someone who performs oral sex on an HPV or HIV-positive partner may also contract the virus.

According to the CDC, you should have an HIV test if you’ve injected drugs, have had unprotected vaginal, anal, or oral sex, or have had multiple partners. You should also be tested if you’ve been diagnosed with an STI.

What are the symptoms of AIDS, and how soon would you know you have it (if you are infected)?

This is a great question, as you tackle a big misconception by recognizing that human immunodeficiency virus (HIV) is not the same as Acquired Immune Deficiency Syndrome (AIDS). Many people make the mistake of believing that it is possible to recognize if a person has HIV. Most often, however, people infected with HIV don’t know they are infected because they don’t feel sick. Some people may get a fever-like illness with fever, rash, joint pains and swollen glands (lymph nodes) immediately after infection. These symptoms usually occur between 1 and 6 weeks after HIV infection has happened and then the symptoms go away.

A person with HIV may look healthy and feel well, but they can still pass the virus on, especially early on in their infection. That’s why you can’t tell if someone has HIV by just looking at them. Over time, however, the HIV virus can develop into AIDS. This typically takes 10-15 years as HIV continues to destroy a person’s immune system, making them more likely to get many different kinds of infections. Once a person with HIV develops any one of a number of infections–such as herpes, tuberculosis, pneumonia, fungal infections–or cancer that causes tumors in the body, they are said to have AIDS, the syndrome of HIV-related immune deficiency.

AIDS affects various parts of the body in different ways. Common symptoms include: fatigue, weight loss, thrush (white patches in the mouth), recurring fever, and diarrhea. Other body systems, such as the brain, kidneys, heart, and genital organs can also be affected by AIDS and will have symptoms specific to that system. As always, if you are unsure about your status it’s always best to get tested for HIV to know for sure because AIDS can be prevented by taking a combination of antiviral medications.

I am an 18 year old female. I only had sex 3 times in my life. All different partners. The 3rd time I caught mono. I am deathly scared that I may have HIV/AIDS too. Is there any correlation between the two? I know I should just get tested if I am so scared about it but I have overly strict and very controlling parents and I desperately need advice on what to do.

There is no correlation between HIV and mono. Mononucleosis is a totally separate virus from HIV so it is not possible for it to cause HIV. The symptoms of mono (flu-like with fatigue, headache, sore throat, feeling lousy in general) are similar to what some people with HIV experience a few days/weeks after being infected, but there is no direct connection between the two. However, if you had unprotected sex with any of your partners, you could have contracted HIV along with any other STI (sexually transmitted infection) and it’s a good idea to get tested.

HIV transmission can occur when infected blood, semen (including pre-cum), and/or vaginal secretions enter the bloodstream. Using condoms is a great way to reduce the chance of transmission. Most people infected with HIV do not know they do not feel ill immediately after infection. However, some people do experience an illness with fever, rash, joint pains, and enlarged lymph nodes.

HIV and all other STI tests are extremely confidential so your parents will not be able to access your testing information or whether or not you were tested at all. Costs for HIV testing vary from free to around $40.00. Many planned parenthoods will work with you to come up with a payment that works for you. Use your Zip Code in this website to find a testing center near you. Once you find one, call ahead of time to make an appointment and to see what you need to bring with you.

Remember, your visit to a clinic and your test results are extremely confidential and the nurses and staff there are trained to keep all information (even the fact that you were there) a secret. I know you’re scared but you’re doing all the right things in reaching out for information and getting tested.
